    One-handed chording keyboard

    Y'all might be interested in a one-handed chording keyboard. It's USB-interfaced, reads to the system as an external keyboard, and is a full 101-key keyboard.

    Unfortunately, you can't buy one. You have to make it yourself. has a lot of information on the design. The inventor has a patent on it, but he also grants everyone the right to build up to five keyboards.

    hey i have one of those. they are not very hard to make at all. john has a very good how to on his site.

    i cheated when i made mine, i mostly used 6-32 all thread. that made it so much easier to adjust and set how long the arms for the 8 switches. i used 1/4 key-stock to connect the arms to the king pin. that gives you adjustment to get everything to fit your hand just right.

    this would be grate in a car if you wanted to mount a keyboard on to the steering wheel its self. just think your hand would never have to move off the wheel when go to the keys.

    oh one other thing....
    if you only have enough room for a number pad
    its not a bad idea. i think i would rather have Q-9(you know the predictive text that cell phones use) if i was using just he number pad.

    does any one know away to make that work on a computer? i havent found a program that will emulate that
